Is DeDust a dex?

Excuse me, but could you clarify if DeDust is indeed a decentralized exchange, or a dex for short? It's important to distinguish these platforms as they operate quite differently from centralized exchanges, offering unique features and potentially higher levels of security and privacy for users. If DeDust functions as a dex, I'd like to know more about its trading mechanism, supported cryptocurrencies, and any unique features it may offer that set it apart from other similar platforms.
